SPECIFICATION forming part of Letters Patent No. 782,109, mated February '7, 1905.

Application filed May 11, 1903 Serial No. 156,560.

To (1 77 u-imm if may concern.-

Be it known that I, MORTIMER E. CooLnY, a citizen of the United States, residing at Ann Arbor, county of *ashtenaw, State of Michigan, have invented a certain new and useful Improvement in Shredding-Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and usethe same, reference be ing had to the accompanying drawings,which form a part of this specification.

This invention relates to shredding-machines, and has for its object a machine intended to produce shreds or thin strips of dough that are adapted to be afterward used in constructing what are known as shredded-wheat biscuits.

In the drawings, Figure 1 is a side elevation. Fig. 2 is a plan of the front end of the beltand of the pressure-roll. Fig. Sisacrosssection of the belt. Fig. at shows a smooth belt with grooved pressure-roll. Fig. 5 shows a grooved belt with the corrugations made separate from the main body of the belt.

A indicates a frame on which there are mounted two rolls B and C on shafts band 1'. These rolls are both smooth and are similar to large broad belt-wheels. Around them is stretched a belt I), preferably of steel, like that used for band-saws. The belt I) is provided with grooves which run lengthwise of it on the external side thereof thatis, on the side which does not come in contact with the rolls I3 and C. A pressure-roll Il, of smooth material, held in suitable adjustable boxes on the frame A, and a feed-hopper F is mounted above the tangential point of the belt I) and the pressure-roll Brackets G support a stripper-comb.H, that is held pi"- otally to the bracket and is held in engagement against the belt I) by a weightK. One

The boxing a of the pressure-roll E is arranged to be adjusted by the same character of adjustment by screwf'.

In the mouth of the hopper F is a force- 't'eed wheel 1 on the shaft of the main drivingwheel w. The main driving-wheel meshes with a gear-wheel on the shaft of the roll B.

Instead of a plain roll E and a corrugated belt I) a grooved roll F, is used in connection with a smooth belt I). The belt I) is constructed with a smooth body IC and with attached strips jj, such construction being used to overcome ditiiculties of construction of the tempered-steel belt I).

'hat I claim is 1. Ina shredding-nnn-hine, the combination of parallel rollers, means for varying the distance between them, a flexible belt traveling on said rollers, said belt being grooved longitudinally and externally, and a pressureroll engaging against the bolt and a stripper engaging against the belt, substantially as described.

2. In a shredding-machine, the combination of an endless belt grooved longitinlinally and externally thereof, means for carrying it, means for actuating it, and a pressure-roll wh'ose axis is transverse to said belt, engaging closely against the high parts of the surface thereof, substantially as described.

I). In a shredding-machine, the combination of a belt grooved longitudinally and externally, rolls on which the belt is carried, means for adjusting the rolls, a pressure-roll engaging against the belt, and a stripper engaging against the belt, substantially as described.

a. The combination of a belt grooved longitudinally and externally. means for supporting and actuating the belt, a pressure-roll engaging against the belt, a feeding device, and a stripper engaging against the belt, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
